Sequoia: A New OpenPGP Implementation in Rust
summary
Sequoia is a new OpenPGP implementation written in Rust that actually shows what was built: a streaming, low-level API focused on usability and memory safety, with concrete solutions for infinite types via dynamic dispatch, boxed-reader recursion and the enormous linked-list cache bug that slowed parsing from 1.5M packets/s to a few thousand, and a custom packet-parser API that preserves streamable packet handles. The crate is already 98% feature complete, ports cut client code to 60% as much code compared to GnuPG.
